Specification of Letters Patent.

Patented Nov. 22, 1910.

Application filed. May 22, 1909. Serial No. 497,720.

To all whom it may concern:

Be it known that I, l VALTER F. BROWN, a citizen of the United States, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented a certain new and useful VVing-Carrier for use on Threshing-Machines, of which the following is a full, clear, and exact description.

The objects which the present invention has in view are: to provide lateral wing carriers for threshing machines and machines of like character, which may be universally mounted upon the majority of such machines of the present standard makes, and which may be detached therefrom; to provide such a carrier which may be retracted into a position where there is no interference when the machine is moved to and from the location in which it is operated; to provide means for adjusting the said carriers to receive from points within a certain radius, which adjustment can be made as, and when, the machine is in operation; and to provide for said carrier, devices whereby the ma terial being handled, may be advanced and automatically released at a given point.

One embodiment of the present invention is shown in the construction illustrated in the accompanying drawings, wherein like characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a side elevation of a threshing machine, having the feeder extended, and being equipped with wing carriers constructed in conformity with the present invention; Fig. 2 is a front elevation of the threshing machine, showing thereon the wing carriers constructed in accordance with the present invention, and in operative position; Fig. 3 is an enlarged side view of one of the wing carriers, and the mountings therefor; Fig. 4: is a cross section of the carrier, as shown in Fig. 3, taken on the line 4-4 of said figure; Fig. 5 is a vertical section of the bracket whereon is mounted the driving gear for operating the carrier, and for the supporting arms of the carrier; Fig. 6 is a detail view of the means for adjusting the position of the delivery end of the carrier; Fig. 7 is a detail view in plan of one of the adjusting joints employed; Fig. 8 is a detail view in plan, showing the mounting for the driving gear, and the double bevel gear connected therewith; Fig. 9 is a side view of the driven sprocket wheel, together with the sprocket chain and carriers connected therewith; Fig. 10 is a detail view in end elevation, showing the carriers in operative position, and the sprocket chain in connection therewith; Fig. 11 is a side view of the elements shown in Fig. 10; Fig. 12 is a top plan view of the same elements; and Fig. 13 is a detail view in plan, showing the construction of the links for the sprocket chain which are employed to mount the can riers. Fig. l l is a detail view on an enlarged scale, partly in side elevation and partly in vertical section, of the boom and connections therefor with a threshing machine of usual construction; Fig. 15 is a detail view on an enlarged scale, of the brackets for holding the booms and the connecting rods between the same for maintaining the vertical position thereof.

Heretofore, where wing carriers have been used, they have depended for support in their extended position upon an overhead structure, employing guy ropes, extending to the outer end of the carrier. Another form has depended upon some stilt or truss construction, supporting the outward extension from the ground or underneath cross framework that interferes with the manipulation of the feeder. The principal objections to these forms of carriers have been that in the former construction, the overhead structure was apt to become entangled with the trees or any comparatively low-lying overhead structure. A further objection to this has been that most of the standard makes of threshers, where such contrivances as the wing carriers are most applicable, provide feeders of many different forms and types of construction, some of which are pivoted to the front of the thresher and tilted up and away and swing on said pivots in order to provide means of ingress for in spection or repair to the inner front mech anism of the thresher proper; others in which the extended carrier part of the feeder folds over the top of the feeder; and again, others in which the extended part folds underneath the feeder and which would interfere with the emplacement of an overhead structure, or of an underneath cross frame structure to be used for the support of wing carriers. The objection to the latter structures has been that when secured in position, any movement on the part of the threshing machine has necessitated the disarrangement of the carriers. Another objection has been that the carrier has remained in a more or less fixed position. It is very desirable, in vthe work that these carriers perform, that the receiving end should be capable of being laterally moved, as the loading station is constantly and gradually changing during the operation of the thresher in front of a stack.

To avoid the objections above noted, I mount the carrier primarily upon the outer end of a boom 14, and upon this boom is pivotally mounted a bracket 15, upon which is carried the weight of the inner or delivery end of the carrler, as hereinafter described. The outer end is carried on a saddle 16, which is held in position by a rod 17 pivotally mounted at 18, in the swinging hinge member 19. The major portion of the weight of the carrier is carried beyond the center of the boom 14, and therefore the supporting strain in the said boom is a torsional one; At the outer end, this torsional strain is received on a long and heavy screwbolt 20, that extends through a head 21, and is screw-threaded into a perforation formed therefor in the bracket 15. The head 21 has an extended flange 22, which rests against the side of the bracket 15, against which the said bracket is drawn firmly by the bolt 20. To further support the bracket 15, there is provided a tie-rod 23, which engages, by means of an eye, with the bolt 20, and is extended through a suitable perforation in the lower end of the bracket 15 and secured by a nut 24. The said tie-rod acts as a brace against any strain exerted upon the lower extension of the bracket 15. The relation between the bracket 15 and the boom 1 1 is regulated by a rod 25 in pivotal relation thereto, said rod being extended from the boom 14. The rod 25 is slidably mounted in a lug 27 which is extended from the side of the bracket 15. The rod 25 is screwthreaded throughout, and is provided with two nuts 28 mounted at either side of the lug 27. By turning these nuts in unison, the rod 25 is advanced or retracted through the lug 27, causing the bracket 15 to swing about the bolt 20, thereby changing the an gular relation between the boom 14 and the arm 15. The object of this shifting of the bracket 15 is to bring to and hold the said bracket 15 to an upright or vertical position relative to the vertical parts of the front of the thresher. This construction is provided with this adjustment as there will be a variance of angle of the boom 14 when attached to difierent makes of machines.

To the lower end of the bracket 15 is pivot'ally connected a socket 29, the lower end of which is provided with U-shaped extensions 30, adapted to engage universal pivots 31 provided at the lower end of the bracket 15. A cotter-pin 32 is driven through the ends of the extensions 30 to retain the socket 29 in position. Into the socket 29 is introduced a screw-threaded rod 33, provided with a groove 3 1 in its inner end, which receives a pin 35 suitably inserted through the walls of the socket 29. The screwthreaded end of the rod 33 is inserted within a pipe member 36, in which it is secured by a suitable screw-thread connection. At the upper end, the pipe member 30 is provided \vitha cap 37, which is hinged to a cap 38 provided to receive the outer end of the rod 17. \Vhen the rod 33 is rotated by any handle, such as 39, or any other suitable device, it turns within the socket 20 in fixed relation thereto, while the threaded connection between the said rod and the pipe member 30, causes the pipe member 30 to be drawn toward or extended from the connection with the pivot 31 at the end of the bracket 15. This action produces the effect of raising or lowering the saddle 16 and the carrier 40 which rests upon said saddle.

By means of the construction thus far-dcscribed, a carrier, such as 4-0, is supported from the boom 14 near its inner or delivery end, and is provided with means whereby it may be raised or lowered-at its receiving or outer end; also whereby the inner or delivery end may be manually adjusted laterally and vertically relative to the feeder, and longitudinally relative to the threshing machine. The boom 14: carries the weight of the carrier trough and the parts attached thereto, mostly by its torsional resistance, and is preferably constructed of suitable pipe of sufiicient weight and size to withstand said torsional strain. The boom 1 1 is secured to the threshing machine at its lower end by the bracketed plate 11, which, in most machines, will be bolted as shown at Fig. 1 to the forward end of the lower side sill of the threshing machine. Said plate-.11 of necessity will be of different forms and shapes to fit the construction of this part of the framing, in different makes of threshing machines and therefore the plate a1 will be special for each make of threshing machine which it is to fit. But the bracket 4-2, which is an integral part of the plate l-.1 will be the same for all makes of threshing machines. It is provided on its outer face, to receive a rounded surface formed on the lower end of the binder bracket 411, which is bound and bolted to the lower end of the boom 14:, with the binder bolts 102 and the cross rods 49, 4:9.

The binder bracket 44 is maintained in its position on the face of the bracket 4-2 by heavy bolt 101, which passes through the lower end of the bracket 41 and the bracket 12. The holes receiving this belt are larger than the bolt, to permit a pivotal. action on the bracket 6L2 without binding.

The upper end of the raised lug or binder bracket 44 is provided to receive cross rods 49. Said rods are screw-threaded at this point, and are provided with a nut 101 on each side of the raised web 46, by the manipulation of which nuts, the booms 141-, are ro tated and the brackets 15 (see'hig. 3) may be adjusted to an upright or vertical position relative to the side of the thresher to which it is attached. The other end of the cross-rods 19 pass through the binder bracket 14 and boom 1 1-, and has a collar on the side, as shown at 45. These cross rods receive the torsional strain on the boom 1st.

By means of the boom 14 pivoting on the bracket 12, the upper end of the boom bracket 15 may b adjusted to its proper position, horizontally relative to the threshing machine feeder, and is held rigidly in said location by the telescope brace 100, which bolts to the side of the feeder or threshing machine at a point where said feeder or threshing machine is not so wide as the lower side sills.

The boom 14 is supported at its outer end by a rod 4-7 secured to the side frame of the threshing machine, preferably by being slidably passed through a lug bracket 18. The end of the rod &7 where it passes through the said lug bracket 48 is screw-threaded and provided with screw H nuts seated at either side of said lug bracket 18, whereby the rod may be taken up or let out and locked in the desired position. As the rod is thus retracted or extended, the free or outer end of the boom 1 1 is raised or lowered, swinging on the bracket lug 42 as a pivot. The length of the rod 47 determines the height of the bracket 15 relative to the delivery point on the threshing machine feeder.

The rods 100, 47, 101 and 45, are to be screwed up tight and fixed in position when they have been adjusted, so that the bracket 15 will have its proper location relative to the threshing machine feeder.

The supporting members of the present invention may be said to be the boom 14-, the rods 47 and brace 100, constituting a tripod arrangement to extend from the frame of the threshing machine, and converging at. the forward end. upon a holding device, directly connected with the wingcarriers.

The frame of the carrier 10 is constructed of any desired material, areferably a lightweight material, which is reinforced by metal hoops 50. Between two of the hoops 50 and extended longitudinally with the said carrier, are provided rails formed preferably from angle-iron 51, the ends of the saddle resting within and sliding upon these rails 51. The carriers may be extended to any suitable length, providing the strength of the structure of the bracket 15 and'the boom 14 will permit. The rod 17 and pipe me1nber 36 may be elongated to any extent, thereby accommodating a carrier of great length. At the inner end of the carrier is provided a chute-like extension 52, which is set at a downward angle from the carrier, so that when the end of the carrier is depressed to accommodate the feeding workmen, the extension 52 will yet remain in a position not above the horizontal. This is very desirable, as it is at'this point that the carrying members of the advancing chain release their hold on the material being handled. If, when released, this material were upon a surface inclined away from the line of delivery, the material would tend to retract, and effect a blocking or massing of the material at the delivery end of the carrier, which is undesirable. The inclination of this part of the carrier trough is also necessary to allow proper driving engagement between the driving sprocket (31 and chain of the conveyer. t also permits the raising of the bracket 15 so that the screw-bolt 71 will at all times clear the driving belt, and the delivery end of the carrier trough to be at its proper relative position to the threshing machine feeder.

Extended longitudinally throughout the carrier is a linked elevator, consisting of an endless chain composed of hooked links 53, each of which is provided with a hook 5 1-, the hooks being adapted to engage the end of the links. Certain of the links 53 are provided with lateral extensions 55 pivotally engaging the carriers 56, nested and bolted together by a long rivet bolt 57. Perforations are provided in the lower extension of the carriers, to receive the lateral extensions 55 of the links 53. When the bolt 57 is inserted and set through the body portion of the carriers 56, the lateral extensions 55 are prevented fromv being withdrawn from the perforations provided in the carriers. The carriers 56 have two tine-likeextensions 58, which are maintained in the upright posi; tion shown in Fig. 11 of the drawings, by tail pieces 59 and 60, which differ in length, as shown in Fig. 12 of the drawings, for the reason that on one side of the carrier chain, the sprockets would interfere with the drop of the tail piece.

The chain is driven by a sprocket wheel 61, which is located at the inner end of the carrier, and extends upward through the floor of the same, the chain being supported at its outer end by a suitable idler 62. The tail pieces 59 and 66 slide upon a sole plate 63, upon which the conveyer chain travels. The inner or delivery end of the carrier trough is supported by a strap bracket 64 securely bolted to the inner rib of the carrier trough, and is hinged to a T-shaped bearing frame 65. The said hinge 6a or strap bracket is radially central with the driving sprocket 61, shaft 66 and bevel gear 67, thereby permitting the outer end of the carrier trough to be raised or lowered without disturbing the alinement of any of the above transmission elements. It is at this point where the carrier trough pivots in the vertical adjustment of its outer end. In the bearing T-frame 65, a transmission shaft 66 is mounted, upon the end of which is fixedly mounted a driving sprocket 61, whose inner hub is housed by an enlarged annular end of the bearing T- frame 65. Said housing is to prevent windin or wrapping of material on the hub or shaf The shaft 66 has also fixedly mounted thereon a bevel gear 67, which is in mesh with the upper side of a double bevel gear 68, whose plane of rotation is horizontal, and which is mounted rotatably on an extended vertical sleeve of the bracket 15. Inside of this sleeve on the bracket 15, there is pivotally mounted the lower end of the T-bearing frame 65, as shown at 69, whose rotary axls is radial with the axis of the gear 68, and is rotatably held in the said sleeve by means of a suitable washer 70 and screw-bolt 71. The other end of the carrier trough may be moved in a horizontal plane (pivoting at this point) without disturbing the alinement of the said elements of transmission. Thus it will be seen that the outer end of the carrier trough may be raised or lowered or swung horizontally in all directions, without in any manner disturbing the alinement of any of the elements of transmission. And the transmitting machinery may be running freely at the time that the outer end of the carrier trough is'being so swung, and moved as above mentioned.

The bevel gear 68 receives its movement from a driving sprocket wheel 72, provided with a bevel gear extension 73, which is in toothed engagement with the bevel gear 68, and is driven by a sprocket chain 74 led from a convenient rotating shaft of the machine to which the wing-carriers are attached, preferably from the shaft that drives the apron of the feeder.

The bearing member for the shaft 66 is framed to form the housings 75 and 76, both of which are adapted to receive a gear 67 in engagement with the gear 68. The engagement of the gear 67 with the gear 68 on the reverse side thereof, will, however, reverse the rotary direction of the shaft 66. This construction provides a simple and eflicient means for reversing the action of the driving sprocket wheel 61 when the same is shifted from the one side of the thresher to the other, or when attached to certain makes of threshers which require a reversal of the drive. 1

WVith an apparatus constructed as above described, the operation would be as follows. The threshing machine on which it is desired to mount the carrier is provided with the plate 41 and the bracket 48 on both sides of the threshing machine. The booms 14 are suitably attached to the brackets 15 in the manner described. The booms are then connected, as described, to the plates 41 and raised to thread the rods 47, through the bracket 48, where secured. The other end of the boom is swung into position with reference to the feeding mechanism of the thresher.

By means of the telesco e brace 100 and the rod 47 when rigidly fixed in position, the bracket 15 is held in a fixed position relative to the side of the feeder. The cross tie-rods 49 are fastened to the pipe binder bracket 44, as previously described, and the nuts 101 are adjusted on the rods 49 so as to bring the bracket 15 to a vertical position relative to the parts of the side of the thresher. The tie rods 47 are adjusted by the nuts 48 so as to bring the bracket 15 to its proper relative height to the feeder carmen The nuts 28 on the eye bolt 25 should be manipulated so as to bring the vertical portions of the bracket 15 into a vertical position relative to the vertical parts of the machine to which it is attached, and all the nuts on all the bolts and rods relative hereto should be drawn up tight and the bracket 15 rigidly fixed in this position. The carriers 40 are placed in position, the free or outer end resting on the ground, or on a trestle, at the option of the operator, until the bracket 64 is secured in position upon the carriers. The saddle 16 is then placed in position on the tracks 51, and the carrier raised, until the pivotal extensions 30 may be inserted over the pivots 31, and the cotter-pin 32 placed in position. If, now, it is desired to move the threshing machine from say the barn to the field, the wing carriers 40 are rotated upon the pivots 69 until the carriers 40 rest along the side of the thresher, where they are suitably bound, or otherwise fastened. It will be seen that the device in this position is snugly held. Arriving at the field, the wings 40 are rotated on the pivot 69, so that the wings extend laterally. By means of the rod or pipe member 36, the outer end is adjusted to the desired height. The carrier may be swung so as to shift the receiving end laterally. The device is now in position to operate. As the grain-bearing straw is thrown on to the carriers, it is advanced by the tines 58 of the carrier belt, and delivered to the feeder of the threshing machine. At the inner end, the tines 58 pass over the depressed ends 52 of the carriers when the tail pieces 59 and 60 drop from the tracks 63 and permit the tines to sway backward upon the line of pull of the chain, thus releasing the material being handled. The tail pieces 59 and 60 are righted to the upright position; when having passed over the outer end of the wings 40, they pass over the idler 62 and again rest upon the sole plate 63. The operation continues as described. When now it becomes desirable to shift the wings so as to change the position of the receiving end thereof, this is done by rotating the rod 33 by means of the handle 39 which operates to raise and lower said end. The carriers are shifted laterally by manually moving the carriers to the position desired. The swing of the carriers about the pivot 69 in no wise interferes in the driving operation of the carrier chains, as the wheel 72 remains in its original relation with the other gear wheels.

Having thus described my invention what I claim as new and desire to secure by Let-- ters Patent is;
